Definitions

  • the invention relates to a method for producing a porous light ceramic material for building purposes according to the introductory part of claim 1 and its use.
  • porous lightweight materials such as are known for example from EP-A-0 007 585, have satisfactory strength and other properties important for construction purposes, such as low weight, but are too expensive to manufacture for numerous applications.
  • a process of the type mentioned at the outset is known from US Pat. No. 4,424,280, in which a slip consisting of clay, foaming agent and other additives is foamed, dried and fired, the viscosity being controlled by the addition of methyl cellulose , however, the material that can be produced when used for construction purposes does not have fully satisfactory product properties, in particular with regard to porosity and mechanical stability.
  • FR-A 2 190 753 a method for foaming an aqueous mixture of clay materials, binders and surfactants by means of compressed air in an open system, i.e. without pressure, is known, but the material that can be produced thereafter does not have satisfactory product properties with regard to heat and / or sound insulation and Has fire resistance.
  • FR-A-2 088 455 in which an already prefabricated foam mixture is admixed to a clay mixture, satisfactory porosity, density and strength properties cannot be achieved either.
  • the invention is therefore based on the object of developing the method mentioned at the outset such that a porous light ceramic material can be produced which can be used both as a light aggregate and for the production of moldings, bricks, in particular also for heat and / or sound insulation purposes and for refractory construction purposes suitable and with simple starting materials in an inexpensive process to lead to pressure-resistant, lightweight moldings, the products produced thereafter should have improved porosity and mechanical properties.
  • the invention also relates to the use of the material produced by the process according to the invention in solid and / or granulate form as a heat and / or sound-insulating material for building purposes, but also as an additive for high-temperature building materials, such as furnace building materials, refractory building materials or the like.
  • a hydraulic binder such as cement.
  • Simple clay and marl can be used as clay, but also Westerwald stoneware clay, porcelain stoneware clay, kaolin, montmorillonite or concrete. It is particularly economical that in the process according to the invention, after drying, unsatisfactory moldings or - in the case of granule production - fine clay foam granulate particles which are eliminated in the screening process can be returned directly to the starting mixture without further treatment, since they are only dried and not are burned and are therefore still fully reactive.
  • the process according to the invention usually proceeds in such a way that clay is mixed with water and plasticizer with the addition of surfactant to form a low-water, thixotropic suspension. Then the foaming takes place in a dispersion system with the addition of compressed air.
  • Conventional dispersing systems such as those sold under the trade name “Hansa Mixer” by the company Hansawerke Lürman, Scdazzling & Co., Bremen, can be used, which add defined amounts of compressed air under pressure (1 to 10 bar).
  • the dispersion system has a further fine metering pump, by means of which liquid can be added before and, if necessary, during the foaming process.
  • a substance which counteracts the liquefaction action of the liquefying agent is advantageously used, for example dilute hydrochloric acid, which makes it possible to produce highly viscous, thixotropic, inherently stable foam suspensions.
  • the inherently stable, thixotropic foam suspension is then dried, the water vapor being able to escape unhindered through the pores due to the high inherent porosity of the material. It is particularly beneficial if the starting material mixture has a relatively low water content.
  • the dried material is usually placed in strands of about 1 cm in diameter, it being possible, for example, to work at temperatures of 200 ° C. with drying times of no more than 5 minutes. This dried mate rial is crushed into granules before firing.
  • the amount of the other additives for example in the production of refractory building materials, is set appropriately, that is to say the addition of alumina, magnesite, quartz and the like, as required by the respective application in this case.
  • the invention is based on the surprising finding that it is possible to produce a product with properties of the type specified above which are significantly improved over the prior art by foaming in a closed system under pressure by means of a defined compressed air supply, which results in the desirable porosity and mechanical properties Properties.
  • a process similar to that according to the invention, directed to the production of a porous adsorbing material, is the subject of EP-B-0 182 793 of the same priority.
  • the drawing which consists of a single figure, shows a flow diagram of the method according to the invention.
  • Such plates or shaped stones can be used as a replacement for glass fiber wool, asbestos fibers or rock wool or rigid foam based on polystyrene for thermal insulation as an insulating material, but also as cladding panels and for light partition walls if a low density is required due to the inadequate resilience of the substrate.
  • a liquefier for example, water glass, calcium polyphosphate, sodium polyphosphate, phosphoric acid, chlorides or sulfates can be used in the process according to the invention.
  • Cement can preferably be added as the hydraulic binder in order to achieve a higher raw strength.
  • granules are expedient which can be obtained by the process according to the invention in that the dried moldings are passed through a crusher to a screening plant which retains a preferred particle size range and discards fines, which can then be returned to the mixer, as can be seen from the drawing.
